CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 583,613, dated June 1,1897.

Application filed February 27, 1897. Serial No. 625,328. (No model.)

To all whom, it may concern.'

Be it known that I, BENJAMIN W. TUCKER, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Oar-Trucks; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had totheaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specication.

The invention relates to car-truck frames, and pertains particularly tothe side frames or beams, the pedestal-frames at the ends of said sideframes, and the transom connecting said side frames.

In accordance with-the present invention the side frames or beams areformed with inwardly-turned upper and lower flanges, be- -tween whichthe ends of the transom are securely riveted, the ends of the transomabutting against the inner vertical surfaces of the webs of the sideframes and having flanges which pass between the upper and lower flangesof' the side frames to which they are riveted. The flange along theupper edge of the side frame projects over the pedestalspaces, and thepedestal-frames are secured to the ilanges at the upper and lower edgesof the side frames, the upper member of the pedestal-frames passing overthe projecting ends of the upper flange of the side frame, which, asabove mentioned, extend across the top of the pedestal-spaces. Thetransom embraced in this application comprises two parall elchannel-beams,an intermediate channelbeam horizontally disposed betweenand riveted to said parallel beams,and short channelbeam sectionsinterposed between said parallel beams adjacent to their upper outerends and riveted thereto and to the top ange of the side frames.

The invention will be fully understood from the detailed descriptionhereinafter presented, reference being had to the accompanying drawings,in which- Figure l is a top view, partly broken away, 'of a portion of acar-truck frame constructed in accordance with and embodying theinvention. Fig. 2 is a side elevation of same, partly broken away andpartly in section, this figure illustrating two forms of pedestalframes,either of which may be employed at will, one being a modilication of theother. Fig. 3 is a vertical section through a portion of the truck-frameon the dotted line 3 3 of Fig. l, and Fig. 4 is a transverse section onthe dotted line 4 4 of Fig. 2.

In the drawings,A designates the side frame or beam, having at its upperand lower edges the inwardly-turned iianges lettered B C, respectively,said iianges being substantially greater in thickness thanV the webportion of the side frame and being of a width about equal to the widthof the guiding-surfaces of the pedestal-frames. The Lipper flange B ofthe side frame A extends outward across the top of the pedestal-spacesD, the projecting -ends of the flanges B being lettered E. The

pedestal-frames F are secured to the ends of the side frame A, and theyare of suitable dimensions to receive the usual axle boxes and springsin the customary manner. The pedestal-frames F comprise the upperhorizontal member G, the outer vertical member I-I, theA Aflange B ofthe side frame A, and is thereto secured by means of rivets or bolts Nand the rivet or bolt O, the latter being centrally over thepedestal-spaces D and extending Vdownward through theoutwardly-projecting end E of said flange B. At the right-hand end ofFig. 2 the lower horizontal member I of the pedestal-frame is formed 'bya bolt l?, passing through the sleeve Q and the outer vertical member Hand the upper horizontal member G of said frame are in an integral pieceor bar of wrought metal, as shown. The present invention is not,however, limited to the formation of the members Gr I-I in an integralpiece nor to the use of the bolt P and sleeve Q as constituting thelower member I of said frame, and hence at the left-hand end of Fig. 2 Iillustrate a form of pedestal-frame IOO in which the upper horizontalmember G and the outer vertical member Il are in two pieces, detachablyconnected by the bolt R, and in which also the outer vertical member Hand lower horizontal member l are in an integral piece, the inner end ofthe lower member l being connected with the vertical member K of saidframe by means of the bolt S. The pedestal-frames shown in Fig. 2 areboth of rectangular outline and are bot-h secured to the flanges of theside frame A in the same manner. The side frames A are rolled beams, andthe upper and lower flanges B C thereof are of substantial thickness andspecially formed to receive the pedestal-frames and the ends of thetransom. The outer projecting ends E of the upper flange B of the sideframe A impart great strength-and security to the pedestals and add tothe efficiency of the truck-f rame as a whole. The rivet or bolt Opasses downward through the upper member G of the pedestal-fram es andthrough the outwardIy-projecting ends E of the upper fiange B and bindssaid parts securely together. The ends of the web portions of the sideframes A are in line with the rubbing-faces of the members K of thepedestal-frames; but since said web of the said frames is not equal inthickness to the width of the members of the pedestal-frame theauxiliary pedestal-piece T is secured through its flange V to the innerface of said web in order that the flange V of said auxiliarypedestal-piece may, with the thickness of the end of the said web,constitute a continuation of the inner side of the pedestal-frame partlyformed by the member K of said frame. The auxiliary pedestalpiece Tfills out the space at the ends of the side frame A between the upperand lower flanges B C of said frame and furnishes a suitableguiding-surface for the axle-boxes. At the upper end of each pedestalwill be provided an integral inverted socket or receptacle X, which inuse receives the upper end of the usual spring located above theaxle-boxes, and said socket in the present instance will preferably befurnished with the end vertical gibs a and top horizontal gibs l) toengage the adjoining surfaces of the pedestalframe. The central portionof the sockets X will preferably be recessed or cut away to accommodatethe head of the bolt or rivet O, as indicated. t

The transom (lettered Y) comprises the transverse parallel channel-beamsd d, the intermediate horizontally-disposed channelbeam e, which isriveted along its edge -flan ges to the web portion of the said parallelbeams, and the short channel-beam sections f, one being at each end ofthe transom and having its flanges turned downward and riveted to theweb portion of the parallel beams d, while the web-surfaces of saidbeam-sections f are about on a horizontal plane with the upper edges ofthe beams d and pass below the upper flange B of the side frame, towhich they are secured by rivets g. The transom at its ends lits betweenthe lower and upper frames B C of the side frames and abuts against thevertical inner face of the web portion of said side frames, and saidtransom is secured at its ends to the side frames by rivets g, abovereferred to, which pass through the flange B and beam-sections f, rivets7i, which pass through the upper liange B, and the upper horizontalflanges of the parallel beams (l, rivets t', which pass through the webportion ot' the intermediate channel-beam c and the lower flange C ofsaid side frames, and the rivets j, which pass through the lowerhorizontal flanges of' the parallel beams d and the lower flange C ofthe side frame. Thus the transom is secured by vertical rivets or boltswhich pass through the flanges B C of the side frame, which flanges areot' substantial thickness and fully able to receive said transom. Theintermediate beam c of the transom extends along the lower edges of theparallel beams CZ and hasits lower plain surface about on the samehorizontal plane with the lower edges of said parallel beams, while itsflanges turn upward and, as above mentioned, are riveted to the webportion of said parallel beams. It will be observed that the ends of thetransom are of rectangular box-like form and are of great strength,rigidity, and durability. The box-like ends of the transom at theirouter extremities snugly fit between the flanges B C and are securelyriveted thereto, as above explained.

In the construction of truck above described the outer ends of thetransom extend outward beyond the central vertical line through therubbing-surfaces for the axleboxes, as indicated in Fig. l, said centralline being represented by the dotted line m.
